Hi,
Saturn is correct: plasma screens are subject to burn-in. DLP (Digital Light Processing) projectors, front or rear, are not.
Keep in mind that as appealing as an inexpensive DLP front projector is, if you want true HD resolution, you have to go way up in price. The inexpensive DLP projectors are HDTV-compatible, but they scale the image to their given resolution, which can still look very good, although it is not true HDTV. The argument for a rear-projection HDTV 16:9 CRT unit at 43 to 47 inches carries weight here, because those projectors will do true 1080i HDTV resolution, whereas similarly priced DLP projectors will not.
Regards,
